スイッチのポートに障害が発生した場合でもサーバーが引き続き LAN に接続されるように、ファイル サーバーに冗長性を提供するのは次のうちどれですか?
正解:A
Explanation NIC teaming, also known as network interface card teaming or link aggregation, allows multiple network interface cards to be grouped together to provide redundancy and increased throughput. In the event of a port failure on a switch, NIC teaming ensures that the file server remains connected to the LAN by automatically switching to another network interface card.
